It looked like Marquart had a stacked double bottle BTA setup in Singapore, but I'm not sure how.

He's got both bottles angled down, though. Mine would leak all over everything. Not to derail this topic further (my original question was about the bracket, which has been ordered so thank everyone! but anyhow)...
FWFI, Lionel Sanders' latest video on wind tunnel testing, has the fastest position for Day 1 as being the double barreled BTA approach (much like Marquart here but angled flat), with the top bottle explicitly positioned to replicate the effect of bottle down the jersey. 1 bottle in that same position (high against the chest) also tested faster.

Obviously comes with the caveat that n=1, and this is day 1 of testing and he hasn't released the day 2 video yet. Yes, but something interesting. It bought him 1 watt. But Jonas says it was 4 watt at 0 deg.
So to come out at 1watt, it was 4 watt at 0 deg and -5 watt at 10deg by the formula they were using.
-5w at 10deg : may want to consider that one at Kona :-)
